Head-Mounted Camera Apparatus
A camera mount includes an arm. The arm has an attachment mechanism at one end of the arm for attaching the arm to a helmet. The arm extends downward in a substantially vertical direction from the helmet when attached via the attachment mechanism to the helmet. The arm has a second attachment mechanism at an opposite end of the arm for attaching the arm to a camera, such that the camera is positioned below a head of a body when attached via the second attachment mechanism to the camera and when the helmet is positioned on the head of the body.

TECHNICAL FIELDEmbodiments of the present invention relate to a head-mounted video camera.
BACKGROUNDTraditional head-mounted cameras, including those capable of shooting video, pictures, or both, mount a camera to the side or top of the head, as seen in
What is needed is a head-mounted camera system in which the weight of the camera will act as a force at the end of a lever arm that effectively reduces the motion of the head and stabilizes the camera and, through inertia, provides better video and pictures than traditional head-mounted camera systems.
SUMMARYA camera mount that suspends a camera below a head of a body such that the weight and position of the camera creates greater stability, and slows movement of the camera relative to movement of the head.
Embodiments are illustrated by way of example, and not by way of limitation, and can be more fully understood with reference to the following detailed description when considered in connection with the figures in which:
Embodiments of the invention provide for a way to attach a camera to the head (using a helmet, a hat, a strap, etc.).
In one embodiment, as illustrated in
In another embodiment, the arm(s) may be fixedly pivotable at the point of attachment to the helmet, and/or at the point of attachment to a camera. While the embodiment illustrated in
Embodiments of the invention put into advantage many factors that are at play when trying to get stable footage with a camera. These include:
The View is Centered:
Camera footage is best centered because any view of the person or their activity is best represented from a central viewpoint. When the view is centered, or substantially centered, handlebars or other items in the frame appear as a person experiences it, as opposed to being offset to the side.
The View is Low:
Action shots typically use a wide-angle lens to capture the view because human vision is near 180-degrees, whereas a traditional camera lens only captures about a 70-degree view (less than half). The difficulty with a wide-angled lens is that it distorts distance such that close objects appear very large and objects in the medium-distance appear much smaller than their actual relative sizes. A person can better “feel” the action in a video when the parts of the footage that are moving (ground, bushes, rocks) are larger on the screen. More often than not the action in the video is below the lens (the ground), not above it (the sky). Given the distortion of a wide-angle lens and the corresponding need to have the camera close to the action it is best to have a POV camera in a lower position.
The Weight (and Strain) is Less:
Mounting a camera on the side of the head, as in the prior art (
The Weight Becomes a Stabilizing Force:
Because the center-of-gravity of a camera mounted according to an embodiment of the invention is at a distance from the head itself, the weight of the camera becomes a force applied at the end of the lever. With reference to
The Weight Naturally Levels the Camera Relative to the Horizon:
The natural “home” position of the camera becomes bottom and center, which levels the camera mount to the horizon. Thus, inadvertent tilt (looking up and down) of the head is neutralized.
You can Use the Tripod Screw:
Cameras often have tripod screens underneath them. These are built as structural supports for the camera. By mounting a camera as it is intended the camera itself is less prone to movement and/or damage.
Tilt and Pan Control:
Cameras (especially large cameras) mounted to the to the head tend to be fixed on either the tilt (vertical movement) or pan (horizontal turning) axis. However, embodiments of the invention can adjust tilt where the camera mount meets the helmet and pan at the point where the camera is mounted to the device.
Movement and Vibration Work Better with Optically Stabilized Cameras:
Many cameras on the market use optical stabilization (which involves the physical movement of the camera lens in opposition of the camera's movement) to stabilize an image during filming. These sensors and motors have speed limitations. They cannot react to high speed jostling or vibrations. A benefit of embodiments of the invention is transforming high frequency movement into lower frequency movement and thereby allowing optical stabilization of the camera to more effectively remove or reduce camera shake.
Movement and Vibration Work Better with Digitally Stabilized Camera and/or Digital Stabilization in Post-Production:
Similar to the above noted advantage that movement and vibration work better with optically stabilized cameras, lower frequency (even at bigger amplitudes) camera shake is preferable to higher frequency movement. In this case it is because with high-frequency vibration each frame of video will be blurred under sudden movement. Digital stabilizing can effectively remove the change in position, rotation and scaling of footage; but it cannot remove blur, thus the footage appears rough and unprofessional. Embodiments of the invention transform sudden jolts into a slower movement that is better captured without blur and more easily handled by digital stabilization techniques.
In an alternative embodiment, the camera can be mounted upside down if that makes a preferable mounting platform (and then the footage flipped right-side-up in post-production). In another embodiment, a secondary stabilizing apparatus may be used between the camera mount and the camera (for example a robotic stabilization) for additional stabilization. In one embodiment, the secondary stabilizing apparatus may be robotic stabilization. In another embodiment, the secondary stabilizing apparatus may be one or more gyroscopic gimbal(s). In such an embodiment, the gimbal(s) may be situated at the point where the arm(s) attach the helmet and/or at the point where the arm(s) attach to the camera.
